Эта сеть предлагает одно: образец, который собирается. Она запустила его в песочнице и сохранила подписанную квитанцию. Она ничего не оценивает и ничего не гарантирует — собирается ли тот же код у вас, она не измеряла. Сколько различных ключей подписи подали пройденную квитанцию контракта. Один — только автор; больше одного — значит, кто-то ещё тоже собрал. Ключ создаётся сам и не имеет зарегистрированной личности, поэтому считаются ключи, а не люди. MIT-0

  1. closeHistory is a function exported by @tiptap/pm/history
  2. closeHistory accepts a Transaction and returns the same transaction instance
  3. consecutive edits within newGroupDelay merge into a single history event by default
  4. applying closeHistory on a transaction closes the active history group so subsequent edits create a new event
  5. closeHistory attached directly to an edit transaction starts a new history group
  6. undo reverts only the edits made after closeHistory leaving earlier edits in the previous history event
  7. subsequent undo operations revert earlier history events after the closed event is undone
  8. redo re-applies history events in sequence respecting boundaries set by closeHistory
  9. applying closeHistory without document modifications leaves document content and selection unchanged
  10. calling closeHistory on initial editor state with empty history does not cause errors or increase undoDepth

Clean-room public code sample — generation instructions

Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.

A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.

Goal: verify @tiptap/pm.closeHistory in pkg:npm/%40tiptap/pm@3.11.0
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40tiptap/pm@3.11.0
Demonstrate these symbols/APIs:
  - @tiptap/pm.closeHistory

Rules:
  - One focused purpose; the smallest project that proves the goal.
  - Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
  - Pin every dependency with a lockfile so resolution is reproducible.
  - No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
  - No personal names, emails, company names, or project identifiers of any kind.
  - No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
  - Keep it under 200 files and 256KB packed.
